` Speccationof `LettersYat-.ent` No. 8,165, dated fune 17, 1851.

To all whom #may concern: i y i Beit known thatV I, SnYMoun` Caravan, of Geneva, in theucounty of Kane and State ofI Illinois, have invented a new and useful Mal chine for` Dressing ,Rived Shingles, called Carversi Rotary Shingle-Machined "of which` the `following is a full andexactgde-` scription.

'Ihe naturejo't "my invention consists in t t ing of 4 parallel sillsw, a, a, a, tenoned into.

passing a rived shingle between two cylinders` furnishedwith knives, the cylinders revolving in contrary directions, the lower cylinder being placed infixed boxes,tthe upper cylinder is made to rise and fall `by means of two inclined planes lupon which the boxes of the upper cylinder rests,V as the shingle c passes through between the cylinders it is iplates c, 0,' on these4 railways I place the 2 planed or dressed on both sides, the upper cylinder being gradually let down by the in cline plane gives the shingle its proper ta per', the shingle beingcarried forward by a carriage of peculiarconstruction moved by means of a rack and pinion, the shingle is urged forward by 4a `detached head block resting upon the carriage and retained by two springs. When the shingle is passed about two thirds of its length betweent-he cuttingc'ylinders the springs arewdisengaged romthe head block and it remains stationary while the shingle having passed between two rollers directly behind the cutting cylinders, the boxes of these rollers being arranged in the same manner as the boxes of the cutting cylinders, these rollers revolving in contrary directionpress upon and pass out the shingle. At `this moment the pinion moving the carriage passes therackirom under it and the carriage stops; to return the carriage to receive another shingle a lever is disengaged froma spring and de pressed by hand, which depresses the rack so that it will return below the teeth of the pinion. The carriage is then drawn back by hand, anotherrived shingle is inserted, and the lever being raised and sustained by a spring the rack is again brought into gear with the pinion and the carriage is again passed forward.

To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation, refer ence being had to the accompanying drawings, where i Figure 1, represents a perspective view of the machine; Fig. 2 represents a longitudinal section showing the combination of pulfleys, drums, and cog wheels, to give motion `to the two rollers, rack andl carriage,y also .showing the guides which prevent the vshingle from vibrating as it is being `passed :between the cutting cylinders; Fig. `3 is a'` `section of the carriage showing the opera- ;tion of the lever i the rack.

in raising and depressing I construct aframeof wood work consistthe cross.` sills t, also the plates c, c, c, c placed dlrect-ly over the sills a, a, and ten! Aoned into the` transverse plates d, CZ, KZ,"

these plates rest on 10 upright posts as shown at e, e; f, f; g, g; and it, it. The posts l1, it, `are tenoned into the rail z'.

j, y', represents 2 railways attached tothe iside r pieces k, le, of the carriage, which are 'connected by the transverse cast iron vvrails Z, m, which are bolted to proper flanges cast g on, or attached to thesides 7c, le. f g In, n, represents the cutting cylinders and V0, 0, the rollers. The journal of the lower Acylinder and roller is suspended'in proper boxes bolted to the under side of the plates c, c; p, p, the boxes of upper cylinder, and rollers, resting on an inclined plane formed `ion the upper edge of the sides cf, k, of the carriage; these boxes rise and `fallbetween the cast iron guides g', g, `as the carriage with l its inclines returns and advances.

1, 11, represents 2 pieces of timber connect-4 ing. thetop of the guides q Q, as shown in the drawing.

s, s, are two elliptic springs attached to the ipieces 7301,' the ends of these springs press ithe boxes p, p, upon the inclined plane. The guides g, g, have flanges at the lower i' end throughwhich they are firmly bolted to the timbers c, c; t, the detached head block l resting on the edge of thecarriage 7c, 7c.

u, u, are ltwo springs attached tothe end 1 of` the cross bar m. `These springs are notched so as tore-tain the head block t, until the end of the spring comes in contact with the `cams fu, fu, which press the springs outward.

`w, fw, are two `plates of metal having a slant in them. These plates are secured to the head t; two pins are placed in the cross bar m, which play in the slants as shown in the drawing.

as, are two pins 'placed in the plates c, c, these pins ypass under the cross lbar fm, but come in contact with the jhead block t and retain it until the carriage is drawn fully back.

y, represents a cast iron bridge tree bolted to the sides of the timbers c, c.

.e represents a roller the journals of which work .in two pillow blocks which have guides passing downward in grooves formed in the bridge tree'y, the lower ends of these guides are connected `to the elliptic spring a, the spring being attached to the under side of thebridge tree, thereforeby means of t-he spring the roller e is pressed downward; I also place a similar bridge tree between the cutting cylinders and the rollers 0, 0, as shown at I), on Fig. 2.

0 represents a bar of cast iron rest-ing on the bridge tree b, which is kept in its place by means of guides, same as pillow blocks in bridge tree y; the bar 0 and bridge tree Z) have their front edges beveled so that the butt of the shingle pressing between the beveled edges raises the bar, and the shingle passes between the bar and the bridgetree.

Fig. 3 shows the rack by which the carriage is moved being guided by the dovetailed grooves in the side 7c of thecarriage.

Z represents the lever working on a pin at e, and connected by a pin at f to the rack.

g, represents a spring attached at L to the side 7c, a notch is formed on the side of this spring at z', which receives the lever d when it is raised up, which brings the rack into y gear with the pinion j.

Z is a small pinion on the end of the shaft of the lower roller 0, which is geared into the cog wheel 7c.

m, m, are cog wheels on the shafts of the rollers o, o, these cog wheels have long teeth to allow the upper roller to rise and fall without putting the wheels out of-mesh. n, is the main shaft working in boxes attached to the posts e, e. v

0 is the driving pulley, P the drum to drive the cutting cylinders. A

g, is a pulley which drives the pulley r on the shaft s; the shaft s works in boxes attached to the braces t.

u, represents a pinion fixed to the shaft s, which gears into the cog wheel c.

o, fu, are small pulleys fixed on the ends of the shafts of the cutting cylinders.

w is an idler pulley having its shaft work- V ing in boxes secured to the under side of the frame c, c; I then pass an endless belt around the drum P, over the upper pulley 11, and under the lower pulley o, then over the pulley w I then place an'endless belt around the pulley g and drum 1, on shaft s, and the machine is completed.

The loperation of this machine is such, that the carriage being drawn outward by hand the head block 2f comes in contact with the pins the carriage stile passing outward the' pins in the bar m, passes along the slants in t-he plates w, until the springs u, u fall behind the head block-a rived shingle is then placed in front of the head block t one end of the shingle rests on a ledge formed on the head block the other end resting on the bridge tree y, as represented by the dot-ted lines in Fig. l; motion being given-to the pulley o, the drum P, communicates a rapid motion to the cutting cylinders at the same time the pulley g gives the motion to the shaft s, which by the cogged wheels u, la,

vand Z gives-motion to the rollers o, o; the

lever being raised by hand falls into the notch z', of thespring g; which brings the rack into gear with the pinion j, and the carriage is passed inward preessing the shingle under the roller s and between the cylinders n., n, the head block t strikes l against the bridge tree y, and being released from the springs u, u, by means of the cams o, the head block remains stationary, and the carriage passes on regularly depressing the upper cutters until the rollers 0, 0, draw the shingle out and deposit it-the rack is then depressed by the lever d, and the carriage drawn back by hand, ready to receive a shingle as first speciied.

Vhat I claim as my invention and desire to secure by Letters Patent is- The arrangement of the head block t, with the springs u, u, cams o, o, the rollers 0, o, and stops fr, for the purpose of passing the shingles between and out from the cutting cylinders; in combination with the arrangement for depressing the upper cylinder while in motion for the purpose of giving a taper to the shingle, the whole cornbined and arranged substantially as set forth in the above specification.
